Synthesis, isolation and characterisation of β-sitosterol and β-sitosterol oxide derivatives

Organic & Biomolecular Chemistry, 2005
Beta-sitosterol is the most prevalent plant cholesterol derivative (phytosterol) and can undergo similar oxidation to cholesterol, leading to beta-sitosterol oxides. The biological impact of phytosterol oxides has only been evaluated in a phytosterol blend (usually of beta-sitosterol, campesterol, stigmasterol and dihydrobrassicasterol).

The effects of sitosterol on serum lipids

The American Journal of Medicine, 1955
Abstract 1.1. The effects of the plant sterol, beta-sitosterol, on serum cholesterol, other lipids and lipoproteins have been studied. Twenty to 25 gm. of sitosterol per day was administered for prolonged periods to fourteen patients on free diets. 2.2.

Quantitation of β‐Sitosterol in Bourbon

Alcoholism: Clinical and Experimental Research, 1991
Four phytoestrogens have previously been isolated and identified in alcoholic beverages. Before studies to evaluate the degree of estrogenicity of these substances can be performed, it is necessary to determine appropriate doses to be administered to experimental animals.

The effects of statins and sitosterols: Benefit or not?

Current Atherosclerosis Reports, 2008
Statins reduce plasma plant sterol concentrations and, less consistently, their ratios to cholesterol in short-term studies. They most likely accomplish this by decreasing their transport protein levels. In long-term treatment with large doses of effective statins, serum plant sterol concentrations and frequently their ratios to cholesterol are ...

Absorbability of β-sitosterol in humans

Metabolism, 1969
Abstract Tritium labeled β-sitosterol was administered orally to 5 normal humans and to 5 terminal patients. Isolation of tritium-labeled sterols from plasma and red blood cells of normal male subjects showed some absorption had occurred, but it was much less than for comparable doses of labeled cholesterol.

Effects of cholesterol and ß-sitosterol in the gerbil

American Journal of Physiology-Legacy Content, 1959
The effect of increasing levels (0–1.0%) of dietary cholesterol has been studied in the Mongolian gerbil. A consistent and proportional elevation of serum cholesterol was observed after one week of cholesterol administration. In addition, the simultaneous administration of ß-sitosterol prevented this hypercholesteremia.

Fate of Beta-Sitosterol in Housefly Larvæ

Nature, 1958
TWENTY different species of insect larvae, distributed among four orders (Orthoptera, Coleoptera, Lepidoptera and Diptera) have been found so far to require sterols as growth factors. All of them, excepting the Dermestidae (Dermestes vulpinus Fabr.1 and Attagenus piceus Oliv.2), can utilize both zoosterols and phytosterols; certain species, however ...
